The following is my mom’s take:

If I remember correctly, this picture was taken summer of 1966, when I was 19, my second summer in Micronesia, and this was taken on Ulithi Island, the first outer island on one of Dad’s medical tours. Dad would usually travel one week a month on the tramp steamer, Yap Islander, to the outer islands to treat patients and train the local med-techs…

…Mike had just flown in on a puddle jumper plane from Guam that touched down on one end of the island and stopped on the other end of the island after breaking really hard. He didn’t know that Dad and I were on the island, so he was very surprised to see me in the midst of a bunch of topless women meeting the plane. He also hadn’t figured out where to look at the women… except in the eyes. Note his lack of tan…

… Mom had traveled to the outer islands many times with Dad and had made many friends. She had let her friends know that I would be coming, and most of the islanders had never seen a teenage haole girl before. The young girls were very eager to meet me. On this island the young people were being taught English by a teacher named Jim Boyken at a small school…

…Dad would have medical clinic and Father Walters would hold mass. I would be taken by hand and showed the village and the island. The houses were made of bamboo and coconut thatching, very clean with breezes flowing tru to make the houses very cool…

…Cooking was done outside on a fire. At each home families wanted to share something with me, either food or coconut water and beautifully made leis made in the Micronesian style. I, in turn would start out my day with many bracelets (and cigarettes) which I shared…

"The "girls by the table"... that was the school's boat. Instead of PE, the students would go out spear fishing for their daily food. One student would stay in the boat to bail out water. When the students caught a fish they would relay thrown them into the boat because the blood attracted reef sharks. According to Dad, if the sharks came too close, the kids would kick them in the nose." Su Tucker (@Damon Tucker)

…The girls were very shy and giggled a lot as we tried to communicate with each other. Pre-pubescent girls wore front and back grass skirts, older girls and women wore beautifully woven lava lavas, a type or sarong made from course white fibers dyed with local dyes. I remember that the girls used turmeric, a yellow spice, in their hair for decoration. One girl asked to borrow my brush and they all shared hair brushing. As you can tell from the picture, their hair was very tightly curled or negroid. They were interested in my hair because it was straight. When they returned the brush, it was immaculately clean…

This is fascinating! My dad was the medical doctor who must have come when your grandfather left. He was Dr. William Henderson and he brought his family: my mom (Sarah) sister (Jamie) and me (Sandie). Dad worked in the hospital and travelled to the outer islands. We lived there for 2 years (summer of 67 until summer of 69) and my sister and I attended only English-speaking class in local elementary school as we were in 2nd and 3rd grades. What an amazing 2 years!!!

WoW !
I happened across this today and was there too, with my sister Patty, 68-69ish I remember Sandie And Jamie Henderson, I thought the were the greatest, My folks and theirs would hang out. I miss the Island and would love to go back someday. I was always out in the brush looking for left over ordnance from WW2 and liked to take bullets apart and make improvised rockets and firecrackers great fun and not safe and sane at all.
